a multiplicity of jewels at the same time.

Heretofore jewels for precision instruments ,such as Watches, gauges,and the like, during their processing had to ybe handled singly, owingto the extremely hard nature of the material out of which they are made.Most Watch jewels are made of synthetic sapphire or ruby and the onlymaterial which can be used to successfully cut or polish this materialis diamond dust and owing to the extreme smallness of these jewels theoperation is carried out on `a single jewel at a time. This materiallyretards production and contributes to the high Acost of manufacturedjewels.

The term oliving which is not found in the English dictionary, yet maybe found in the Swiss and French, is directed to the rounding of theinternal bore ofthe jewel so as to present a single line of contact withthe staff to thereby reduce friction. Inasmuch as the jewel industry ispractically a new industry in the United States and there being noadequate term in the English dictionary to express this operation, theterm foliving is used throughout the specication.

It isthe object of this invention to provide an apparatus by means ofwhich a group of jewels `maybe olived at one and the same operation.

It is a further object of the present invention to provide a rotatingmember adapted to give both rotation and lateral movement to the jewelsbeing olived.

VA further object of the present invention is to provide a holder forthe jewels which can be positioned at any angle with regard to arotating element.

A still further object of the present invention is toprovide means formounting a group of jewels in contact with a rotating member, thesupporting means being adjustable to a desired position withregard tothe rotating member.

Itis a still further object of the present invention to provide rests ateach side of the rotating member to accuratley govern the distance ,thejewels are held from the rotating member.

Fig. 2 is a side view.

Referring to the drawing, a base I supports standards 2 and 3 which havea shaft 4 journaled therein, a brush 5, having long brass bristles andend plates 6 and l, xed on said shaft and spaced from said standards bybushings 8 and 9. Pulleys IIJ, II, and I2 mounted on said shaft providemeans for driving the brush at different speeds from the same motor (notshown).

A ball I3 having a threaded rod I4 and an adjusting nut l5, is mountedin the base and supports a straight bar I6 and a spring bar I'l toprovide a universal support for the jewel holder. A clamping .bolt I8bears against the spring bar I1 and is threaded through the straight barIIi-to securely clamp the bars I6 and II about the ball I3. A spring I9bearing against the spring bar I'I and the clamping bolt I8 providesadditional resiliency in this connection, while a handle rod 29 is usedto correctly position the entire mounting.

Secured to the back of the straight bar I6 is a spring strip 2I whichbears against a cross bar 22 and holds it firmly in a notch on thestraight 25 bar while an additional handle member 23 ex- Vclamped by theclamps 29 and 30, the wire being drawn taut by manipulation of the nut28.

Adjustable rests 35 and 36 are provided at each side of the rotatingbrush and have a curved bearing surface 31 having approximately the samecurvature as the rotating brush to receive and support the ends of thejewel carrying wire 33. The rest 3B is pivoted to a link member 38 at 39intermediate of its length and to link member 49 at 4I. The link member40 is pivotally supported at 42 on the support 3 and carries anadjusting screw 43 which is threaded into an extension 44 and is xedlyand. rotatably held at the base I. The movement of the rests 35 and 36is such that the supporting surface is always parallel or concentricwith the curvature ofthe brush. This provides very accurate individualadjustment of the rest 36 with relation to the surface of the rotatingbrush. 'I'he rest 35 is supported in a like manner and adjusted byadjusting screw 45 to give that rest individual adjustment.

In operation the wire 33 is charged with diamond dust in the well knownmanner by rolling the relative soft iron or copper wire on a steel platein a mixture of diamond dust and while using a steel bar to press thematerial into the surface of the wire. This is a hand operation and is anormal method used to charge wire with diamond dust. The jewels 34 arethen strung on the wire in a number limited only by the desire of theoperator and the size of the brush being used. The wire is clamped inthe clamp 29 and stretched taut to the clamp by hand, the nut 28 beingtightened on the threaded rod 21 to bring the wire to the desiredtautness. The rests 35 and 36 are adjusted to such a position that theysupport the jewels in brushing contact with the brass'bristles of therotating brush so that the jewels are rotated on the charged wire,

the bristles not only giving the jewels rotation but also lateralmovement causing the internal bore of the jewels to be olived. Thislateral movement is accomplished by a slight canting of the abradingwire on which the jewels are carried. This slight canting causes thejewels to move from one end of the wire to the other as the wire isnever more than half filled with jewels. Thus a lateral movement isgiven to the jewels by the rotating brush simultaneously with therotating movement, the lateral motion on the wire serving to preventwearing of the wire in any one particular spot. The operator by graspingthe rod 23 can now move the entire jewel mounting on the:

ball I3 so that the motion of the jewels is accelerated, the jewelsworking themselves toward the high side of the wire, which is of course,shifted from side to side by movement of the jewel mounting; in thismanner the jewels are worked both ways across the length of the wire,are giving rotation and lateral movement by means of the rotating brush,the nal result being that the internal bore of the jewel is rounded atthe endsLthis rounding being commonly termed by jewel makers as olivingWith the apparatus herewith described it is possible to produce a groupof jewels in which the oliving'is Very nearly identical. With the method'now being used where a single jewel is olived by an operator it is verydicult to produce jewels having uniform oliving. It must be borne inmind that these jewels are extremely small,

being of a size corresponding to the head of an ordinary pin, some beingsmaller and some larger and the almost impossibility of measuring thisoliving when handling the jewels individually. This oliving operationwhich formerly required from 10 to 20 seconds on an individual jewel isnow carried out on as many as200 jewels at a time in approximately 30seconds.
